Post by THUFIR HAWATHow do you know that your charging system works? Basically, if the voltage on the batter reads above 13 when the throttle is twisted?It's a chinese clone of a Honda, 49cc. Just trying to determine whether the batter is the problem or not.

For about $10 or so, you can get a 6 LED monitor, whereeach LED lights up at a specific voltage (12, 12.5 ...14).Find a point in the wiring where there's voltage only whenthe bike's turned on and hook up here. Makes a very nicemonitor while you're riding and gives you full time infoon how the charging system's doing.

A good starting point in your troubleshooting would be toget the battery charged and load tested. After it's charged,you should see it holding 12.4-12.5 volts or so. If it can'thold this kind of voltage you may need a new battery.

Also, take a very careful look at the battery cable connections.A loose + or - cable can fool you into thinking you have abad battery or charging system.
